1.4 Special Functions

Auto MDI/MDI-X Function

This function allows the TP port to auto-detect the twisted-pair signals
and adapts itself to form a valid MDI to MDI-X connection with the
remote connected device automatically .

Auto-negotiation Function

When TP port is set on Auto-negotiation mode (SW1:ON), it is featured
with auto-negotiation function and full capa bility. It performs a negoti a­tion process for the speed and duplex configuration with the connected
device automatically when each time a link is being established.

Far End Fault Function

The FX port is facilitated with this function, which conforms to IEEE

802.3u 100BASE-FX specifications. When the FX port detects a link
failure on its receiving circuitry , it will send out an FEFI (Far End Fault
Indication) signal to the remote connected device to indicate a remote
fault is detected. It also is capable to receive FEFI signal sent from the
remote link partner. Upon receiving an FEFI signal, it indicates a link
failure occurred on the transmitting path. This function allows the con­verter to report a fiber link fault even when a link failure occurred on
transmitting fiber cable.

-11-

Link Fault Pass Through Function

When this function is enabled, a link fault detected on the TP port will
force a link down on the FX port. Similarly , a link fault detected on the FX
port will also force a link down on the TP port. As illustrated in the
following figure, this function allows to pass TP link fault to the remote
link partner a nd makes the converter like a TP ca ble extender .

2. Installation

2.1 Unpacking

Check that the following components have been included:

• Installation guide (or contained in the product CD)

• 10/100 Media Converter

• One AC power adapter
If any item is found missing or damaged, please contact your local reseller

for replacement.

2.2 Mounting the Device

Desktop Mounting

The media converter can be mounted on a desktop or shelf. Make sure
that there is proper heat dissipation from and adequate ventilation around
the device. Do not place heavy objects on the device.

Wall Mounting

The media converter also can be mounted on a wall. On bottom of the
device, wall mounting hole is provided for wall mounting.

Installation into Center Chassis KC-1300

The media converter also can be installed in KC-1300 center chassis. The
center chassis provides the power supply to the converter . Up to 16 units
can be installed in one chassis. Unscrew and remove the cover of the
center connector before inserting the converter into the chassis. Refer to
the operation manual of center chassis KC-1300 for more information.

2.3 Applying Power

Before you begin the installation, check the AC voltage of your area. The
AC power adapter which is used to supply the DC power for the unit should
have the AC voltage matching the commercial power voltage in your area.

The AC Power Adapter Specifications

AC input power: AC power voltage of your area, options -

Rated AC120V/60Hz DC7.5V 1A
Rated AC230V/50Hz DC7.5V 1A
Rated AC100V/50-60Hz DC7.5V 1A
Rated AC100V/50-60Hz DC5V 1A
Rated AC240V/50Hz DC7.5V 1A

Steps to apply the power to the converters are:

1. Connect power adapter DC plug to the DC input jack located on the

back of the converter before connecting to the AC outlet.

2. To ensure against accidental disconnection, tie the DC cable with

the cable tie located the back of the converter.

3. Connect the power adapter to the AC outlet.

4. Check Power LED indication.

Since the WDM single fiber media converters use different wavelengths
for transmission and receiving respectively, the link partner device lo­cated on the remote end of the single fiber should match the wavelength
used on the single fiber converter.

3. Optional Configuration Settings

The media converter provides additional configuration settings which
are user-inaccessible. The settings are built on the board inside the prod­uct case. The settings are provided for technical installers to adapt the
converter to fit some specific application needs.

3.1 User Inaccessible Jumpers

The setting jumpers are not accessible by users generally. For accessing
these jumpers, the upper case must be removed from the product. Re­moving the case must be performed by an authorized and experienced
technical person. The setting jumper block is located on the position
shown below:

The setting functions are as follows:

JP 1 Forwarding mode setting Open - Store-and-forward mode

Short - Smart-forward mode

JP 2 802.3x function setting Open - Enable

Short - Disable

JP 3 FX port duplex setting Open - Full duplex mode

Short - Half duplex mode

-19-

3.1.1 Forwarding Mode Setting JP1

The following table lists the forward method used in different TP to FX
conversions:

JP1 Setting TP port to/from FX port Forward method

Store-and-forward 10BASE-T to 100BASE-FX Store and forward

100BASE-TX to 100BASE-FX Store and forward

Smart-forward 10BASE-T to 100BASE-FX Store and forward

100BASE-TX to 100BASE-FX Direct conversion

On smart-forward mode, the converter can change to direct conversion
automatically when it detects same speed on both TP port and FX port.
Direct conversion method converts the signal between TP port and FX
port without storing the received packet on one port then forwarding to
a nother port. The medi a converter operate s with the mini mum latency.

Note:

1. In direct conversion, be sure both devices connected to the TP port

and FX port have same duplex mode for proper transmission.

2. In direct conversion, 802.3x function is disabled and the media

converter will not generate pause frame, but just forwards the
received pause frame directly from one port to another port.

3. In direct conversion, the media converter is not limited to the

maximal length of the receiving packets.

-20-

3.1.2 802.3x Function Setting JP2

IEEE 802.3x function is the flow control method used for full duplex op­eration on TP port and FX port under store and forward mode. This
method uses pause frames for one port to stop further transmission from
its link partner.

3.1.3 FX Duplex Setting JP3

This setting is used to set the duplex mode of the FX port.

3.2 JP1-JP3 Factory Default Settings

The factory default settings for JP1, JP2, and JP3 are as follows:

JP 1 Open Store-and-forward mode
JP 2 Open 802.3x function is enabled
JP 3 Open FX port full duplex
